OLYMPIA, Wash. -- Olympia police say burning torches were hurled at a police substation and patrol car and more than 20 people were detained during a protest.

A police spokesman told KIRO 7 that the torches were quickly extinguished, and there was no damage to the building or injuries to protesters during the demonstration.

One protester, Jeff Berryhill of Olympia, told The Olympian newspaper the demonstration Friday night was against police violence, especially a recent shooting death.

In that case Jose Ramirez-Jimenez was fatally shot in neighboring Lacey following a police chase.

Police reported that about 20 demonstrators were detained and photographed, and three were arrested for investigation of rioting and violating police orders.

Police identified those arrested as 30-year-old Walter R. Cuddeford, 23-year-old Peter A. McCoy and 20-year-old Daniel K. Wilson. Police Sgt. Paul Johnson said all three could be charged with attempted arson, a felony.
